ELECTROMAGNETIC IGNITER.

Specification of Letters Patent.

To all whom it may concern:

Be 1t known that I, CHARLES S. BEARDs- LEY, a citizen of the UnitedStates of America, and a resident of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Electromagnetic Igniters, of which the following is aspeciiication.

-M- My invention relates to improvements in electromagnetic igniter orsparking devices especially adapted for use in connection with gasengines of automobilesand the like, and has for its object the rovisionof suchan igniter which will avoit certain defects'hereinaftei pointedout, and will be sim le and cheap in construction while withstandingordinary usage for long periods. In devices of this class which ofnecessity are attached directly to the engine cylinder-head, the severalparts are subjected to a high degree of heat, and in view thereofcertain precautions must be taken in order to avoid deterioration of theparts. For example, in a device of thischaracter wherein springs areemployed the heat within a short time destroys the temper of the springand causes imperfect action of the device. Even if precautions are takento remove the spring as fail as possible from the engine cylinder itbecomes necessary to provide ground joints within the irniter in orderto insure a close fit and exc ude some of the heat from the actuatingspring. Accordingly, I have constructed an igniting device whereinsprings are altogether avoided and a positive actuation is insured byproviding a relatively strong permanent magnet normally to close thecircuit of the igniter.

Further .details of construction and the relation of parts may best begathered by rel'- erence to the accompanying drawing in connection withwhich the specification and claims are t0 be read, wherein-- Figure I isa vert-ical sectional View through an igniting device constructed inaccordance with my invention. Fig. II is a View in elevation of theCasin g wherein the several parts are mounted, and Fig. III is a diagramillustrating generally the electrical relation ol' the parts.

Throughout the several figures of the drawing I have indicated similar4parts byfthe same character of reference.

` Referring 'first to -Fig. I, a general idea of the simple structureofmy invention will at once bc gathered.- Theroin the 'perforated casinga is provided with upper and lower heads a, a2, the latter of which isscrewthreaded below and is designed to be -`inserted within the engine eTlinder-head (not shown in the drawing). I ithin said casing a isprovided an electro-magnet b which is series-connected with the contactarm c. This arm is pivotally mountedA to be'aotuated by the respectivearmatures c', c2 carried upon the non-magnetic rocker-bar c3. Adjacentto the electro-magmet is thepermanent magnet d which normally causesthecontact point c4 to engage with its contact' c5, adjustablymoiintedwithin the casing-herida2 and normally extending within the enginefcyl-.inder-head. Suitable insulating members i, i', preferablyasbestos-faced, are provided within the casing and serve to mount theelectro-magnet and permanent vmagnet in position for the properactuation and engagement of the igniter contacts. Circuit is'establishedthrough the insulated binding screw e, spring c and stud c2 with whichone terminal of the magnet winding is connected, the other terminalbeing grounded upon the frame f which carries the contact arm c.'

The mechagical relation of the partsisa parent from an inspection ofFig. I, wliilie the electrical relation in use will best be gathered byconsidering Fig. III, wherein the battery B is intermittently closedthrough the igniter circuit containing in series-relation thecircuit-closer C, the windingsE of electro-magnet b, and the contacts c,c5 which ai'enormally held closed'by means of the permanent magnet d,conductor A completing the circuit of the several parts.

The operation of the device will be perfectly clear when it is notedthat the electroN magnet will be energized upon each closure of theconnected circuit, thereby actuating the contact arm to separate thecontacts c4, c5 andcause a momentary spark between these parts, which,as stated, are positioned within the engine cylinder-head. 'Immediatelythe circuit is opened the electro-magnet will be denergized, and thepermanent magnet d will serve to close the series contacts. Dependingupon the speedv of rotation of the circuit-closer C, one or more sparksfor igniting the charge within the engine cylinder will bc producedbetween the contacts c* c5, but
